I cannot confirm the temperature problem on my Clevo Laptop. It's used as a desktop replacement so does all the tough stuff. With make -j9 it isn't even used 100% probably you could adjust your portage niceness?

1. Thanks for introducing me to the i7z tool, which I didn't know about earlier. I also enabled cpu msr support in my kernel which I didn't have earlier (and i7z requires it for detailed statistics), so now I can see the turbo clocks too .

2. Second, I meant that the CPU temperatures are high when it runs at full load, for example while compiling kernel with "make -j4" or emerging some gentoo packages like gcc (without any renicing). (And even then, I have never noticed any slowdown.) For example, running a simple openssl benchmark (which runs 8 threads)

Code:

# for i in $(seq 10); do openssl speed aes-128-cbc -multi 8; done

will make my CPU temperature go to 70s or 80s after a minute or so as shown in the i7z output below. (Can press ctrl+c at any time to stop the benchmark.)

Cool tool I've installed it now - temperatures much higher than my machine - is your fan working propperly?

I think I didn't make myself clear enough:

1. This CPU runs hot when running on full load. Period.

If one wants to reproduce the benchmarks in the article, at least the CPU intensive ones, the high temperatures should be noticeable. Things may vary depending upon the cooling system of the notebook (how good the fan and ventilation systems) are, room temperature and other things. But in a normal room at about 23C, it would be hard to keep the temperatures below 65C or 70C when the CPU is running at close to 100%. And that is hardly a surprise with 4 cores running at 2.5 GHz turbo and consuming close to 40W for CPU alone. While to most people interested in this CPU, it should be obvious that high performance comes with high power dissipation, I just stated explicitly as to how hot it gets.

2. I don't have any issues with my machine, hardware or software. Even if any, they are minor and very reasonable and I am perfectly happy with it. Furthermore, it is not worth my time and effort to get some marginal gains.

Overheated Notebooks ...

Same here on all my desktop replacements in the last several years. Browsing many repiews, HP Pavilions (on my 5th now) have value for $, on slow usage. But professional reviewers, + YouTube tutorials, + HP's official website, show the HP do not know how to create notebook cooling. Mine breakdown just after warranty expires.

Only one model of one brand has self-cleaning, optimal air-flows. Can't remember now - I buy on $ value as they breakdown. YouTube tutorials will assist breakdown delay. USB external fans, routine cleaning are compulsory - but the sellers carefully do not explain this well. Their motives: more sales, more profits.
